Overview of this book

The drastic surge in the demand for XR development has led to an imminent need for comprehensive resources, learning material, and overall know-how in this area. This one-stop resource will ensure that professionals venturing into XR development can access all XR-related techniques to build appealing XR applications, without relying on Google every step of the way. This book is your guide to developing XR applications with Unity 2021.3 or later versions, helping you to create VR, AR, and MR experiences of increasing complexity. The chapters cover the entire XR application development process from setting up an interactive XR scene using the XR Interaction Toolkit or AR Foundation, adding physics, animations, continuous movement, teleportation, sound effects, and visual effects, to testing and deploying to VR headsets, simulators, smartphones, and tablets. Additionally, this XR book takes you on a journey from the basics of Unity and C# to advanced techniques such as building multiplayer applications and incorporating hand- and gaze-tracking capabilities. By the end of this book, you'll be fully equipped to create cutting-edge XR projects for engaging individual, academic, and industrial use cases that captivate your audience.

Understanding sound theory and Unity’s audio system

In the subsequent sections, we will delve into the fascinating physics of sound waves and explore how Unity’s robust audio system allows us to manipulate these properties with its diverse range of audio components. Our journey begins with an introduction to the fundamentals of sound, the nature of sound itself, and its defining features – frequency and amplitude.

What are frequency and amplitude?

Sound, in essence, is a form of mechanical energy that propagates as a wave through a medium – most commonly, air. Simply put, mechanical energy is energy associated with the motion of objects. When an object vibrates, it displaces the surrounding air particles, setting off a chain reaction of particle displacement that travels outward in the form of a sound wave.

The two main parameters describing a sound wave are frequency and amplitude.

Frequency is the number of complete wave cycles per second,...
